include_dir_bytes = "0.2"
embed_staticfile = "0.2"
and use them like this:
#![feature(plugin)]
#![plugin(include_dir_bytes)]
extern crate iron;
extern crate mount;
extern crate embed_staticfile;
use iron::prelude::*;
use mount::Mount;
use embed_staticfile::EmbedStatic;
fn main() {
let mut mount = Mount::new();
mount.mount("/assets/", EmbedStatic::new(include_dir!("../assets")));
Iron::new(mount).http("localhost:3000").unwrap();
}
